just to make a few things clear, the aem bypass valve only works when the filter is completely SUBMERGED in water. as far as a damp filter, you dont need to worry, the engine wont suck in water off the filter unless its submerged in water. remember the filter has 360 degree breathability. only time your engine will suck in small amounts of water is if you have an iceman ram air intake for daily driving, that is just retarded. unfortunatley one of my friends did that. hydrolock is not fun at all...lol
